Given the list of pKa values, which acid will have the largest amount of conjugate base present in the solution at equilibrium?

Acid: Pka:
H20 15.7
NH3 38
HCL -8
NH4+ 9.2

H2O

NH3

NH4+

I believe that the answer to this is HCl. I converted the pKa values to Ka, then wrote the ionizaton equation, and then wrote the Ka expression and found HCl. What are we thinking?
